1. The problem statement, all variables and given/known data
An electron (charge -e, mass m) and a positron (charge +e, mass m) revolve around their common center of mass under the influence of their attractive coulomb force. Find the speed of each particle v in terms of e, m, k and their separation r ?
2. Relevant equations
F= kq1q2/ r^2
3. The attempt at a solution
Can you guys give me a hint on this one ? Should I find the angular speed then ?
